Elephantiasis of right upper eyelid

This diagnosis code signifies a chronic, severe lymphedema affecting the right upper eyelid, characterized by gross thickening and hardening of the tissues. It results from lymphatic obstruction, leading to significant swelling and disfigurement.

This code is appropriate when documentation clearly indicates elephantiasis specifically impacting the right upper eyelid. It should be used for patients presenting with persistent, non-pitting edema and fibrotic changes of the right upper eyelid due to lymphatic dysfunction.

• Ensure laterality is accurately documented (right upper eyelid).
• Distinguish from other forms of eyelid edema or inflammation; elephantiasis implies chronic, severe lymphatic involvement.
• Consider co-reporting underlying causes of lymphatic obstruction if known and documented.
